If you want to show someone how to do something on a computer, you don’t need to spend a lot of time to write step-by-step instructions any more. Just turn on ZD Soft Screen Recorder, do the things you want to show, everything happening on screen will be recorded into a video file. In the meantime you can use your mouse to draw some markups directly on screen to annotate your operations, and if you have a microphone connected you may add your narration simultaneously. And finally you can cut the unwanted parts of a recorded video, or join some separately recorded videos into one video, and then send or share the video to the ones need help, perfect!
